Express踩坑系列之GET请求

首先我在app.js中允许了所有请求

// 允许所有的请求形式 
app.use(function(req, res, next) { 
  res.header("Access-Control-Allow-Origin", "*"); 
  res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
  next();
});

Express封装了GET请求，使请求更加简易

var express = require('express');
var router = express.Router();

/* GET loves listing. */
router.get('/', function(req, res, next) {

  // 获取参数
  var query = req.query;
  console.log("get请求：参数", query);

  res.send('hello，world');
});
